Re: 300 WBY brass for 7mm STW
Well I have some norma 300 weatherby brass so I guinea pigged this deal for you. I ran a norma case thru stw fl die filled it with 72 gr of 7828 and seated a 162 amax and squeezed it off. That was a very mild load from the book. Out popped a nice norma stw case. It does measure .02 shorter than regular stw brass.
